Does Your Vehicle Leak Oil?

If Yes, then You've Navigated to the Right Place. Bar's Leaks has got You Covered.

This product works in two ways to help solve most any seal type leak. 1) The seal restorer additive restores seal size, flexibility and elasticity lost due to engine heat, age and high mileage. 2) The seal polymer works by building a polymeric film around the rear main seal and also filling in any groove worn into the crankshaft by the seal.

What are the symptoms of a rear main seal leak?

Depending on the severity of the leak the first thing you may notice is the oil level going down. The next thing that happens is spotting, where you will find oil spots, located on the driveway or garage.

Will Bar’s Leaks Rear Main Seal Repair work on other oil leaks?

Yes. Even though it is specially designed to seal rear main leaks, it also works better than a conventional stop leak on all other engine oil leaks. This includes the timing cover seal, cam seals, O-rings and other seals and gaskets.
